Science in Sport Go Isotonic Energy Gel with Caffeine, Cola Flavour, 60ml (30 Packs)

I’m not a coffee lover, but I was recommended these for my workouts. I used to feel nauseous after exercising, but after taking one of these, I felt energized enough to do the whole workout again! They’re great for recovery. I wouldn’t recommend using them outside of exercise or physical exertion, though.

Super sweet, but not sickly. I love these gels.

Go down with no issues, taste is inoffensive and they give the required boost. Only small issue is they can be a little fiddly to open and you end up getting sticky gel on your hands that you have to deal with for the rest of your run

love these

I bought these in the hope that they may give me that bit extra when out on my bike, I tried the double espresso and I have never tasted anything so horrible, apart from ginger beer perhaps.This tastes nothing like coffee, didn't give me any edge at all and when I got back home one of the side effects that I had was that I couldn't stop eating, then I felt like crap, the come down of the caffeine probably.

One of the best gels I've ever tasted. I usually intersperse with with SIS vanilla during triathlon but they've stopped vanilla. I have to.limit the use of these for the sake of caffeine overdose but 15min after taking the kick comes in

Used these gels on my last three rounds of golf and scored my best results in a long time. Much easier than carrying mushy bananas around. Very happy.

I regularly use these supplements during half marathons, and endurance training, and they are really superb. I generally take one about an hour before I run, and then a second just before the mid-point for a late energy boost when my reserves are running low.The flavours are great, cola being my favourite, they are very easy to take mid-exercise (and my stomach can be very fussy!) and to my surprise, they are really not overly sweet - which is really refreshing.Don't confuse these with post-exercise supplements, they do not offer rehydration support, or rebuild support, they are really just to give you a boost before and during exercise.My only note of caution is that the caffeine in these sachets can have a naughty side effect - a laxative one. So be sure that you don't get caught short by overdoing it with the caffeine during a run!
